Figure 8: A side-view diagram of the grasping components of two antegrade suture passing devices: (a) Without offset, and (b) with offset. The dotted line shows a desired needle projection perpendicular to the inferior arm and shaft of the device. However, we commonly observed the needle penetrate the tendon distal to the grasping window, as represented by thesolid line. In a thick tendon as illustrated in this diagram, even when the needle penetrates perpendicular to the device it travels obliquely through the tendon and exits distal to the superior arm of the grasper. This effect is less when using devices with offset grasping arms (B)
